This specification covers the requirements for heat treated aluminum alloy die forgings@ hand forgings@ and ring forgings@ produced under additional mechanical property control to ensure known mechanical properties for parts used in aerospace critical applications. This specification also covers the requirements for forgings furnished in the F or 01 conditions which will ultimately be used in the heat treated condition. Classification: The aluminum alloy forgings shall be furnished in the following alloys@ tempers and forms@ as specified (see 6.2.1): Alloys and tempers: Form: Forgings shall be furnished in the form of die forgings@ hand forgings or ring forgings. If the form is not specified@ manufacturers may use any form of forging most convenient.
